CLAIM: An extract from French maritime pine bark ‘containing proanthocyanidins (plant pigments with antioxidant properties), organic acids and other biologically active components’. A study published in the Journal of Sports Medicine and Physical Fitness found that recreational athletes taking a daily supplement of 100-150g of pycnogenol reported reduced muscle pain and cramping because of its ability to improve blood flow to the muscles and control free radical damage.
EXPERT VERDICT: ‘There is some research to suggest a daily pycnogenol supplement may help to protect muscle fibres from the rise in free radicals that can occur immediately after exercise. However, more studies are needed to prove this supplement can reduce muscle pain and cramping.’
